Abstract
A method and device for generating an adjustable signal includes a voltage generator configured to continuously adjust an output voltage and output the voltage, a ΣΔ modulator configured to output a digital signal of pre-determined-cycle based on the output voltage and a reference voltage, a counter configured to count the number of a target level in the digital signal of a pre-determined number of cycles, and a digital signal generator configured to generate a target signal based on the number of the target level. The method and device may improve the accuracy of the generated signal while remaining the same feel of continuous adjustment.
